Police detained a 3-year-old boy and questioned him about his sexual activity after learning that he was having sex with children, police in the United Kingdom.

Durham police said that the three-year-old has been interviewed by investigators after being accused of sexually abusing other children.

Police launched the investigation after allegations arose that the child engaged in sexual activities with two other children.

The other two children were five and seven years old at the time of the sexual activities. Police said that they questioned more than 1,000 children who were accused of sexually abusing other children.

Police said that the fact that children are abusing other children is very worrying.

Police blamed the increase of the sexual abuse cases on kids’ distorted ideas taken from the Internet and from being abused by other children.

The head of Child Protective Services said that these figures are only the tip of the iceberg. Police warned that children are now at risk not only from online predators and street gangs, but from other children too.
